After relating a rather equivocal adventure of a husband and wife, who implored Greatraks to cast out the devil of dissension which had crept in between them, St. Evremond thus sums up the effect he produced on the popular mind:—"So great was the confidence in him, that the blind fancied they saw the light which they did not see—the deaf imagined that they heard—the lame that they walked straight, and the paralytic that they had recovered the use of their limbs. An idea of health made the sick forget for a while their maladies; and imagination, which was not less active in those merely drawn by curiosity than in the sick, gave a false view to the one class, from the desire of seeing, as it operated a false cure on the other from the strong desire of being healed. Such was the power of the Irishman over the mind, and such was the influence of the mind upon the body. Nothing was spoken of in London but his prodigies; and these prodigies were supported by such great authorities, that the bewildered multitude believed them almost without examination, while more enlightened people did not dare to reject them from their own knowledge. The public opinion, timid and enslaved, respected this imperious and, apparently, well-authenticated error. Those who saw through the delusion kept their opinion to themselves, knowing how useless it was to declare their disbelief to a people filled with prejudice and admiration."

About the same time that Valentine Greatraks was thus magnetising the people of London, an Italian enthusiast, named Francisco Bagnone, was performing the same tricks in Italy, and with as great success. He had only to touch weak women with his hands, or sometimes (for the sake of working more effectively upon their fanaticism) with a relic, to make them fall into fits and manifest all the symptoms of magnetism.

Besides these, several learned men, in different parts of Europe, directed their attention to the study of the magnet, believing it might be rendered efficacious in many diseases. Van Helmont, in particular, published a work on the effects of magnetism on the human frame; and Balthazar Gracian, a Spaniard, rendered himself famous for the boldness of his views on the subject. "The magnet," said the latter, "attracts iron; iron is found everywhere; everything, therefore, is under the influence of magnetism. It is only a modification of the general principle, which establishes harmony or foments divisions among men. It is the same agent which gives rise to sympathy, antipathy, and the passions." ["Introduction to the Study of Animal Magnetism," by Baron Dupotet de Sennevoy, p. 315.]

Baptista Porta, who, in the whimsical genealogy of the weapon-salve, given by Parson Foster in his attack upon Dr. a Fluctibus, is mentioned as one of its fathers, had also great faith in the efficacy of the magnet, and operated upon the imagination of his patients in a manner which was then considered so extraordinary that he was accused of being a magician, and prohibited from practising by the Court of Rome. Among others who distinguished themselves by their faith in magnetism, Sebastian Wirdig and William Maxwell claim especial notice. Wirdig was professor of medicine at the University of Rostock in Mecklenburgh, and wrote a treatise called "The New Medicine of the Spirits," which he presented to the Royal Society of London. An edition of this work was printed in 1673, in which the author maintained that a magnetic influence took place, not only between the celestial and terrestrial bodies, but between all living things. The whole world, he said, was under the influence of magnetism: life was preserved by magnetism; death was the consequence of magnetism!

Maxwell, the other enthusiast, was an admiring disciple of Paracelsus, and boasted that he had irradiated the obscurity in which too many of the wonder-working recipes of that great philosopher were enveloped. His works were printed at Frankfort, in 1679. It would seem, from the following passage, that he was aware of the great influence of imagination, as well in the production as in the cure of diseases. "If you wish to work prodigies," says he, "abstract from the materiality of beings—increase the sum of spirituality in bodies—rouse the spirit from its slumbers. Unless you do one or other of these things—unless you can bind the idea, you can never perform anything good or great." Here, in fact, lies the whole secret of magnetism, and all delusions of a similar kind: increase the spirituality—rouse the spirit from its slumbers, or in other words, work upon the imagination—induce belief and blind confidence, and you may do anything. This passage, which is quoted with approbation by M. Dupotet in a recent work ["Introduction to the Study of Animal Magnetism," p. 318.] as strongly corroborative of the theory now advanced by the animal-magnetists, is just the reverse. If they believe they can work all their wonders by the means so dimly shadowed forth by Maxwell, what becomes of the universal fluid pervading all nature, and which they pretend to pour into weak and diseased bodies from the tips of their fingers?

Early in the eighteenth century, the attention of Europe was directed to a very remarkable instance of fanaticism, which has been claimed by the animal magnetists, as a proof of their science. The convulsionaries of St. Medard, as they were called, assembled in great numbers round the tomb of their favourite saint, the Jansenist priest Paris, and taught one another how to fall into convulsions. They believed that St. Paris would cure all their infirmities; and the number of hysterical women and weak-minded persons of all descriptions that flocked to the tomb from far and near was so great, as daily to block up all the avenues leading to the spot. Working themselves up to a pitch of excitement, they went off one after the other into fits, while some of them, still in apparent possession of all their faculties, voluntarily exposed themselves to sufferings, which on ordinary occasions would have been sufficient to deprive them of life. The scenes that occurred were a scandal to civilization and to religion—a strange mixture of obscenity, absurdity, and superstition. While some were praying on bended knees at the shrine of St. Paris, others were shrieking and making the most hideous noises. The women especially exerted themselves. On one side of the chapel there might be seen a score of them, all in convulsions, while at another as many more, excited to a sort of frenzy, yielded themselves up to gross indecencies. Some of them took an insane delight in being beaten and trampled upon. One in particular, according to Montegre, whose account we quote [Dictionnaire des Sciences Medicales—Article "Convulsionnaires," par Montegre.] was so enraptured with this ill usage, that nothing but the hardest blows would satisfy her. While a fellow of herculean strength was beating her with all his might with a heavy bar of iron, she kept continually urging him to renewed exertion. The harder he struck the better she liked it, exclaiming all the while, "Well done, brother; well done; oh, how pleasant it is! what good you are doing me! courage, my brother, courage; strike harder; strike harder still!" Another of these fanatics had, if possible, a still greater love for a beating. Carre de Montgeron, who relates the circumstance, was unable to satisfy her with sixty blows of a large sledge hammer. He afterwards used the same weapon, with the same degree of strength, for the sake of experiment, and succeeded in battering a hole in a stone wall at the twenty-fifth stroke. Another woman, named Sonnet, laid herself down on a red-hot brazier without flinching, and acquired for herself the nickname of the salamander; while others, desirous of a more illustrious martyrdom, attempted to crucify themselves. M. Deleuze, in his critical history of Animal Magnetism, attempts to prove that this fanatical frenzy was produced by magnetism, and that these mad enthusiasts magnetised each other without being aware of it. As well might he insist that the fanaticism which tempts the Hindoo bigot to keep his arms stretched in a horizontal position till the sinews wither, or his fingers closed upon his palms till the nails grow out of the backs of his hands, is also an effect of magnetism!

For a period of sixty or seventy years, magnetism was almost wholly confined to Germany. Men of sense and learning devoted their attention to the properties of the loadstone; and one Father Hell, a jesuit, and professor of astronomy at the University of Vienna, rendered himself famous by his magnetic cures. About the year 1771 or 1772, he invented steel plates of a peculiar form, which he applied to the naked body, as a cure for several diseases. In the year 1774, he communicated his system to Anthony Mesmer. The latter improved upon the ideas of Father Hell, constructed a new theory of his own, and became the founder of ANIMAL MAGNETISM.

It has been the fashion among the enemies of the new delusion to decry Mesmer as an unprincipled adventurer, while his disciples have extolled him to the skies as a regenerator of the human race. In nearly the same words, as the Rosicrucians applied to their founders, he has been called the discoverer of the secret which brings man into more intimate connexion with his Creator; the deliverer of the soul from the debasing trammels of the flesh; the man who enables us to set time at defiance, and conquer the obstructions of space. A careful sifting of his pretensions—and examination of the evidence brought forward to sustain them, will soon show which opinion is the more correct. That the writer of these pages considers him in the light of a man, who deluding himself, was the means of deluding others, may be inferred from his finding a place in these volumes, and figuring among the Flamels, the Agrippas, the Borris, the Boehmens, and the Cagliostros.

He was born in May 1734, at Mersburg, in Swabia, and studied medicine at the University of Vienna. He took his degrees in 1766, and chose the influence of the planets on the human body as the subject of his inaugural dissertation. Having treated the matter quite in the style of the old astrological physicians, he was exposed to some ridicule both then and afterwards. Even at this early period some faint ideas of his great theory were germinating in his mind. He maintained in his dissertation, "that the sun, moon, and fixed stars mutually affect each other in their orbits; that they cause and direct in our earth a flux and reflux not only in the sea, but in the atmosphere, and affect in a similar manner all organized bodies through the medium of a subtile and mobile fluid, which pervades the universe and associates all things together in mutual intercourse and harmony." This influence, he said, was particularly exercised on the nervous system, and produced two states which he called intension and remission, which seemed to him to account for the different periodical revolutions observable in several maladies. When in after-life he met with Father Hell, he was confirmed by that person's observations in the truth of many of his own ideas. Having caused Hell to make him some magnetic plates, he determined to try experiments with them himself for his further satisfaction.

He tried accordingly, and was astonished at his success. The faith of their wearers operated wonders with the metallic plates. Mesmer made due reports to Father Hell of all he had done, and the latter published them as the results of his own happy invention, and speaking of Mesmer as a physician whom he had employed to work under him. Mesmer took offence at being thus treated, considering himself a far greater personage than Father Hell. He claimed the invention as his own, accused Hell of a breach of confidence, and stigmatized him as a mean person, anxious to turn the discoveries of others to his own account. Hell replied, and a very pretty quarrel was the result, which afforded small talk for months to the literati of Vienna. Hell ultimately gained the victory. Mesmer, nothing daunted, continued to promulgate his views, till he stumbled at last upon the animal theory.
